This may be widely known, but I called Trackimo this AM to inquire about when the 3G version would be available (they currently use 2G, which is winding down in the next few years). They just received the 3G units, and they aren't even on their website yet - you need to call their 800 number to order. Existing 2G units are $139 including a year of service. New 3G units are $169 including a year of service.
